This from this morning's Herald
Mr Peters has referred questions about the Spencer Trust to his brother Wayne Peters, who won't give any details about it.
Sir Robert has sought assurances that the $25,000 he gave for New Zealand First's 2005 campaign through the Spencer Trust made it to the party.
Sir Robert said he was prepared to probe other donations made previously to Mr Peters.
"Honestly, these are police matters of course," he said yesterday.
He was waiting for a response from NZ First to a letter he wrote last week to MP and former party president Dail Jones, asking about the donation.
Sir Robert said he had given Mr Peters another $150,000 - $50,000 when he started New Zealand First, $50,000 towards his Winebox legal costs and $50,000 in the mid-1990s.
Sir Robert said while he was not yet looking at the other $150,000, he was prepared to "delve" if Mr Peters was to attack him.
"If he wants to take me on, I'm not bragging about this, but I certainly won't tolerate lies and deceit being told about me," he said.
New Zealand First has not declared any donations since he donated.
The money could have been lawfully laundered from the Spencer Trust to other legal entities and to the party in smaller amounts.
Party president George Groombridge says he has never heard of the Spencer Trust. The Electoral Commission noted that the statute of limitations had expired for prosecution of electoral law offences related to donations returns for 2005.
